Guizhou the Unicom network quality analysis system based on alarm information and performance data collected by the network resource information , and network management system , using a variety of assessment tools , a variety of mathematical models to provide objective data on the operational quality of the network , network construction analysis means. The system uses a state-of-the-art data warehouse and OLAP analysis techniques . From the design of the mechanism , the data is organized , in terms of the time span of the stored data , the data warehouse is the system to store and manage data best choice . OLAP problem from different angles to observe and understand the operation and maintenance , and the ability to quickly obtain query results , enables operators from the accumulation of a large amount of historical data in the data warehouse fast, accurate extraction data , presented by the upper tool data chart presented . User submits a query by page , the data warehouse management module will query semantics into database can identify sq1 statement . For each analysis topic semantic model OLAP modeling . Guizhou the Unicom network quality analysis system to provide a summary for a variety of network indicators , forecasting , including : the operation of the network analysis model , network assessment model , early warning and analysis model , holidays prediction model , network size prediction model . To provide users with a simple interface and powerful analysis capabilities , and user-friendly for a variety of analytical decision-making . Analysis results in accordance with user needs to provide a variety show , including tables and various graphics . Network quality analysis contains the the five analysis model : trend analysis , an analysis , comparative analysis, the chain analysis , distribution analysis . This paper describes the network quality analysis system architecture and functional modules call , after the description of the structure of the data warehouse modeling . Finally, through the analysis of the system , its characteristics are summarized .
